Glad you like it!
I could post the shaders online if you would like. But to use them you do need to know a bit OpenGL and GLSL. Let me know if you would like that!
(I am not doing so immediately, because I would have to comment it, and I am streaming right now. ;))
And yes, our game, and so all graphical effects are made in my own graphics engine/library, which I intend to make open source as soon as I get around to it.
